Offshore detention of asylum seekers
Australia has international obligations to protect the human rights of all asylum seekers and refugees who arrive in Australia, regardless of how or where they arrive and whether they arrive with or without a visa.
While asylum seekers and refugees are in Australian territory (or otherwise engage Australia's jurisdiction), the Australian Government has obligations under various international treaties to ensure that their human rights are respected and protected. These treaties include the International Covenant on Civil and Political Rights (ICCPR), the International Covenant on Economic, Social and Cultural Rights (ICESCR), the Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (CAT) and the Convention on the Rights of the Child (CRC). These rights include the right not to be arbitrarily detained.
So I can conclude that the Australian "pacific solution" is against human rights.
People who flee their country in order to escape to safety for sure don't expect to receive an atrocious treatment from the country should help them.
Few other countries go to such lengths to deliberately inflict suffering on people seeking safety and freedom.
